Abstract

An operation method in a mobile communication system is provided to improve the convenience of users and minimize a waste of radio resources due to unnecessary call connections by providing an information message on the basis of subscriber change information in case that request for a call connection is received to a phone number for which subscribers have been changed. If a call connection request to a destination number is received from the first MS(Mobile Station)(S100), a BTS(Base Transceiver Subsystem)/BSC(Base Station Controller) judges whether the destination number is valid(S105). In case the destination number is unused, the BTS/BSC transmits an associated information message to the first MS(S110). Meanwhile, if the destination number is connectable, the BTS/BSC fetches information about the destination number(S115). Based on the fetched information, the BTS/BSC judges whether subscribers for the destination number have been changed(S120). If so, the BTS/BSC confirms the call details between the first MS and the second MS having the destination number and judges whether a call record after the subscriber-changed date exists(S125). If not, the BTS/BSC transmits a subscriber change information message, which announces that subscribers for the destination number have been changed, to the first MS(S130).

At this time, when the user's mobile communication terminal and phone number is changed, if another user attempts to connect to the phone number before the user's change, the user is connected to another user according to the change of subscriber, causing inconvenience to both users. Done. That is, the current mobile communication terminal and the mobile communication system do not provide the change information even if the subscriber for the predetermined telephone number is changed, so if the subscriber is changed, the call connection is not possible, and the changed new user is caused by the wrong call. Not only will it cause inconvenience, but it also wastes money on unnecessary call connections.

Therefore, an object of the present invention is to store the subscriber change information when the subscriber for a predetermined phone number is changed, so that the change information guide and call connection based on the stored change information when a call request to the corresponding phone number is received. The present invention provides a method for operating a mobile communication system.

The operation method of the mobile communication system according to the present invention for solving the above problems is a step of receiving a call connection request to a predetermined telephone number, if the subscriber of the telephone number is changed, based on the subscriber change date and the outgoing telephone number Retrieving the call history to the telephone number, and transmitting a subscriber change guide message indicating that the subscriber has been changed, if there is no call history after the subscriber change date.

In addition, the operation method of the mobile communication system according to the present invention comprises the steps of receiving a call connection request to a predetermined telephone number, if the subscriber of the telephone number is changed, retrieving the last call date between the telephone number and the outgoing telephone number; Making a call when the last searched date is after the subscriber change date, and when at least one of a case where the last searched date is before the subscriber change date and a call history does not exist, the subscriber. Sending a change announcement message.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a block diagram showing the configuration of a mobile communication system according to the present invention.

As shown in FIG. 1, the mobile communication system according to the present invention includes base stations BST01 to BST03 for transmitting and receiving data to and from a plurality of mobile communication terminals MS01 to MS03 located in a predetermined region, and at least one base station BST01.

In addition, the mobile communication system includes a database (not shown) in which subscriber personal information, subscriber change date for a predetermined telephone number, and subscriber change information including a call log are stored. Here, the database is connected to the base station and the base station controller (BST / BSC) to provide information on a predetermined telephone number at the request of the base station and the base station controller (BST / BSC). In this case, the database may be included in a base station and a base station controller (BST / BSC) or may be separately constructed and connected. It can also be included in the communication network N separately from the base station and base station controller BST / BSC. At this time, the database stores the data received from the home location register (HLR, not shown), visitor location register (VLR), etc. of the mobile communication network to the predetermined telephone number at the request of the base station and the base station controller (BST / BSC) Information and subscriber change information can be provided.

Here, the communication network N includes a network such as a mobile communication network, a packet data network, or a wireless Internet network, and may be formed as a network in which at least one network is interconnected. At this time, the form of the network may be changed according to the data and voice call processing scheme of the mobile communication terminal, and accordingly, a predetermined wireless access network may be included in addition to the base station and the base station controller (BST / BSC).

Here, the base station and the base station controller (BST / BSC) of the present invention is an example of the access network device for connecting and transmitting data or voice calls according to the request of the mobile communication terminal, as described above in the data and voice call processing scheme Accordingly, a predetermined radio access network device may be used, and each base station and base station controller (BST / BSC) may be separately constructed or one device.

The base station and the base station controller (BST / BSC) is to determine the location of the received telephone number and the corresponding mobile communication terminal according to the call connection request for the call connection of the predetermined mobile communication terminal, corresponding to the corresponding through the communication network (N) By requesting a call connection to the base station and the base station controller (BST / BSC), a voice call is made possible.

At this time, the base station and the base station controller (BST / BSC) determines whether the incoming call number of the requested call is valid, and transmits a predetermined voice announcement message to the calling mobile terminal requesting the call connection according to the subscriber change information of the incoming call number. The base station and the base station controller BST / BSC perform a call connection to the mobile communication terminal of the corresponding phone number or release the connection with the calling mobile communication terminal at the request of the calling mobile communication terminal.

Here, the base station and the base station controller (BST / BSC), if the subscriber of the incoming telephone number is changed, based on the call history between the calling telephone number and the incoming telephone number of the mobile terminal requesting a call connection, outgoing movement after the subscriber change date If there is no call history for the communication terminal, a subscriber change guide message indicating that the subscriber has been changed is transmitted, and if there is a call history after the subscriber change date, the call is immediately connected without a separate notice message.

In addition, the base station and the base station controller (BST / BSC) retrieves the last call date between the outgoing call number and the incoming call number, and if the last call date is earlier than the subscriber change date, and transmits a subscriber change guide message indicating that the subscriber has changed; In the case where the last call date is after the subscriber change date, the call is immediately connected without a separate notice message.

In addition, the base station and the base station controller may provide a voice announcement for the changed phone number in response to a request of the calling mobile terminal when the information on the changed phone number of the subscriber change information of the received phone number is disclosed.

Here, the call history is requested between the outgoing call number and the incoming call number to enable at least one of the base station and the base station controller (BST / BSC) to provide voice guidance according to the change of the subscriber as described above. It may include a control unit (not shown) for determining that the voice guidance according to the details is performed and to issue a predetermined control signal.

For example, the base station and the base station controller (BST / BSC) determines the validity of the second telephone number when a call connection is requested from the first mobile communication terminal MS01 to which the first telephone number is assigned to the second telephone number. Call between the first mobile communication terminal MS01 and the second mobile communication terminal MS02 by transmitting a signal to the base station and the base station controller according to the position of the second mobile communication terminal MS02 to which the second telephone number is assigned. To make it possible.

At this time, when the second switch number requested by the first mobile communication terminal MS02 is not valid, a voice guidance message indicating the absence of the corresponding phone number is transmitted to the first mobile communication terminal MS01. In addition, if the subscriber is changed, the call history between the first mobile communication terminal MS01 to which the first phone number is assigned and the second phone number is retrieved. If the call history does not exist after the subscriber change, the subscriber is changed. The voice message is sent, and if there is a call history after the change of subscriber, the call is connected to the corresponding phone number without a separate guide message.

Here, when the subscriber of the second telephone number is changed, when the change information is set to be disclosed by the subscriber before the change, the base station and the base station controller (BST / BSC) informs that the subscriber has changed as described above, the first move In response to a request of the communication terminal MS01, the voice guidance message notifying that the subscriber changed to the third telephone number before the change of the third telephone number may be transmitted.

In this case, the mobile communication terminal receiving voice guidance by the mobile communication system as described above inputs a communication unit (not shown) for communication with a base station, a memory (not shown) storing a plurality of phone numbers and call details, and a user command. A communication unit according to a receiving input unit (not shown), a display unit (not shown) for outputting an operation state, a speaker (not shown) for outputting voice, a microphone (not shown) for inputting voice, and a user command input through the input unit It includes a control unit (not shown) for requesting a call connection, and controls the input and output of the data so that the voice guidance message received from the base station or the base station controller is converted and output through the speaker.

When the mobile communication terminal receives the voice guidance message from the base station or the base station controller as described above with respect to the requested call connection, the mobile terminal converts it and outputs it through the speaker, and according to the user command input through the input unit, the base station and the base station controller ( BST / BSC) continues to request connection or disconnection. In addition, it is possible to request change information and a change phone number for the corresponding phone number.

Looking at the operation of the present invention configured as described above are as follows.

When the base station and the base station controller (BST / BSC) receives a call connection request from a predetermined mobile communication terminal, for example, the first mobile communication terminal (MS01) (S100), the telephone with the received telephone number according to the call connection request exists The validity of the number is determined (S105).

If the received telephone number is unused or does not exist, the guide message is transmitted to the first mobile communication terminal MS01, which is the calling mobile terminal (S110). At this time, the guide message may be guided by voice, and a message of a text or a video may be transmitted according to a call connection method.

If the incoming call number is an active, connectable phone number, information about the incoming call number is called. Here, the base station and the base station controller (BST / BSC) requests the information on the received telephone number from the database including the information on the received telephone number (S115).

Here, the information on the received telephone number includes subscriber information on the telephone number, current location information of the mobile communication terminal to which the telephone number is assigned, and call history within a predetermined period.

The base station and the base station controller BST / BSC may determine whether the subscriber of the received telephone number has been changed based on the information on the received telephone number, and receives the originating telephone number, that is, the first mobile communication terminal MS01. The call history between the second mobile communication terminal MS02, which is the mobile communication terminal to which the phone number is assigned, is searched (S120).

When the subscriber of the received telephone number is changed, the call history with the calling telephone number requesting the call connection is searched based on the subscriber change date, and it is determined whether the call history exists after the subscriber change date (S125).

Here, the last call date between the incoming call number and the outgoing call number can be retrieved.

If the call history exists after the subscriber change date between the incoming call number and the outgoing call number, the signal is transmitted to the base station and the base station controller based on the location information of the second mobile communication terminal MS02 to which the incoming call number is assigned. A call connection between the first mobile communication terminal MS01 of the outgoing telephone number and the second mobile communication terminal MS02 of the incoming phone number is enabled (S140).

Alternatively, when the searched last call date is after the subscriber change date, the call connection between the first mobile communication terminal MS01 of the outgoing call number and the second mobile communication terminal MS02 of the incoming call number is enabled (S140). ).

In other words, if there is a call history between the outgoing call number and the incoming call number after the change of subscriber, the signal is transmitted so that the call is connected without a separate procedure.

On the other hand, if the call history does not exist after the subscriber change date between the incoming call number and the outgoing call number, a subscriber change guide message indicating that the subscriber for the incoming call number has been changed is the first mobile communication terminal MS01 of the outgoing call number. Transmit to (S130). In this case, the subscriber change guide message may be guided including at least one of text, voice, and video according to a communication access method, but voice is preferably guided.

Alternatively, if the searched last call date is earlier than the subscriber change date, and if at least one of the call details does not exist, the subscriber change guide message is transmitted to the first mobile communication terminal MS01 as described above.

Regarding the transmitted subscriber change guide message, it is possible to select whether to continue the connection by the first mobile communication terminal MS01, and according to the data received from the first mobile communication terminal MS01, If selected, the signal is transmitted to the base station and the base station controller based on the location information of the second mobile communication terminal to which the incoming call number is assigned, and the first mobile communication terminal MS01 of the outgoing call number and the second of the received call number. The call connection between the mobile communication terminals MS02 is enabled (S140).

If the 'continuous connection' is rejected by the first mobile communication terminal MS01, the connection is terminated (S145).

Here, a signal flow between a first mobile communication terminal MS01 of an outgoing telephone number, a base station and a base station controller for making a call connection according to a call connection request, and a second mobile communication terminal MS02 to which an incoming phone number is assigned As shown in FIG.

That is, when a call connection request is received from the first mobile communication terminal MS01 to the base station and the base station controller BST / BSC (S200), the base station and the base station controller BST / BSC are connected to the requested call connection as described above. The subscriber change guide message for the received telephone number is transmitted to the first mobile communication terminal MS01 based on the information on the received telephone number (S205). In the case of a voice call, it is preferable that a voice message is transmitted as a subscriber change guide message, and in the case of other data calls, a voice message can be transmitted as a text message. It may also be transmitted in a video message.

When the connection request is received by the first mobile communication terminal MS01 even when the subscriber is changed (S210), a signal for notifying the reception of the call is transmitted to the second mobile communication terminal MS02 to which the received phone number is assigned. (S215), it is set to enable mutual call connection (S220). Here, the base station and the base station controller (BST / BSC) is the second mobile communication terminal (MS02) in accordance with the type of communication network and data to determine the location, and transmits a signal to the base station and base station controller of the local area of the second mobile communication terminal It is possible to make a call between the MS02 and the first mobile communication terminal MS01.

Can be.

That is, as shown in FIG. 4, the subscriber change guide message is transmitted to the first mobile communication terminal MS01 in FIG. 2 (S300), and the data received from the first mobile communication terminal MS01 is determined. It is determined whether a change telephone number request of the previous subscriber is received (S305). Here, the base station and the base station controller (BST / BSC) may transmit a separate guide to the first mobile communication terminal (MS01) to enable the selection of the previous subscriber's information with the subscriber change guide message.

If the previous subscriber's change phone number request is not received from the first mobile communication terminal MS01, as shown in FIG. 2, the first mobile communication terminal transmits a guide message according to 'continue connection' (S320). Call connection between the MS01 and the mobile communication terminal to which the reception telephone number is assigned is performed.

When the change subscriber number of the previous subscriber to the received telephone number is requested by the first mobile communication terminal MS01, the base station and the base station controller BST / BSC determine whether the change telephone number of the previous subscriber of the received telephone number is disclosed. Determine (S310).

At this time, when the change telephone number of the previous subscriber of the received telephone number is disclosed, information about the changed telephone number is transmitted to the first mobile communication terminal MS01 (S315). That is, when the subscriber of the received telephone number is changed, the change telephone number is registered by the previous subscriber, and if the disclosure of the changed telephone number is set, it is possible to guide accordingly. In this case, the change phone number information is preferably guided by voice, but may be transmitted as a text or an image according to a connection method. That is, when the telephone number of the previous subscriber of the second telephone number is changed to the third telephone number, when the change telephone number is disclosed as described above, the third telephone number can be guided.

On the other hand, if the change phone number for the previous subscriber of the incoming phone number is set to private, a notification message indicating that the change phone number is private is transmitted to the first mobile communication terminal (MS01), as shown in FIG. By sending a guide message for the 'connection' (S320), the call connection proceeds or disconnects according to the selection of the first mobile communication terminal (MS01).

As described above, the base station and the base station controller (BST / BSC) does not immediately connect a call when a call connection request is made, but transmits a subscriber change guide message to the mobile communication phone of the outgoing call number according to whether the incoming call number is changed. .
